Media UK The Register writes that the new iPad 4G data connection will only work in the United States, and users cannot easily switch network.

The new iPad recently launched in San Francisco is the first Apple device networked LTE (long-term evolution), the world standard is generally called 4G.

Although in accordance with world standards and can use Verizon’s network and AT & T, The Register said the new iPad LTE connectivity will not work anywhere else in the world.

Between two carriers in the U.S., users can not even move easily from one operator to another operator because of the frequency of the two different networks.

Unlike 3G, which is in the same band internationally, or 2G, which can work on multiple bands, LTE is highly fragmented with more than 32 different bands.

In the United LTE has been used by AT & T and Verizon in the 700MHz band, but the operator still require different hardware for the iPad, and in England the whole band has been fully used for Freeview terrestrial television.

It’s worth noting, The Register stressed, the term 2G, 3G, and 4G has no legal definition, so that anyone is free to mention anything to their handset at will.

In the United States generally claimed that HSPA + network as 4G.

And in Europe, The International Telecom Union uses the term “4G” for more than 100Mb/second speed network, but the reality of the abuse of the rule that the term was remarkable, says The Register.

AT & T runs two LTE networks in the U.S., one in a block of 2.1 GHz which is generally used for 3G networks, and the other in what is known as “Class 17, 700MHz”.

The latter refers to the band AT & T purchased through a tender in 2008 with different frequencies across the U.S., but it works on frequencies between 704MHz to 787MHz.

While Verizon LTE running a single network, known as “Class 13, 700MHz”, operating at frequencies between 746MHz and 787MHz.

The operator in the U.S. have been busy lobbying the regulators, the FCC, to require all devices support all LTE 700MHz band, but so far no luck.

So when people buy a new iPad, with 4G connectivity, they have to decide whether you want to work with the iPad Verizon’s network, or iPad for AT & T network, and outside the U.S. for its 4G connection may not be able to work with the same device.

Apple is one of the leading companies in the world of IT in the market. Why? The reason for their popularity is simple because of their functions and user-friendly application development iPhone coming in their products like the iPhone, iPad etc. The company provides products in the field of hardware, development tools and systems of operation. These products can easily gel with each other so that developers can make apps iPhone ideal for users.

The developer tools Code X offers a user-friendly, an iPhone development environment that includes everything you need to build a great Mac OS X and iOS apps. They iPhone developers provide an environment that makes it convenient for them to develop different applications such as instruments.

Characteristics in the instruments

Characteristics in the various instruments are developed below.

Data recording
This is simple, once the user has submitted the application and data tools for the analysis by clicking the red button while specific data is stored for later analysis.

Visual comparison
With this feature, iPhone users can view the different relationships between the different types of data stored and displayed, or the same data for multiple testing.

Drill down
This unique feature developed by iPhone developer in which the developer and the user can see the peaks on the graph and data can solve the problem in the execution of code using Xcode.

Reading
With the ease of playing back an ad hoc test is created in which the user interaction with the application is stored and can be played back to see the effects in the performance by the modified code.

Instrument library
This feature not only exciting but also the users of iPhone developers to choose the instruments in the library of low level CPU, file activity and network and can move on to more advanced tools and user events.

Zombie Detection
We all know that zombies are found in the same way, when there are system crashes or there are application errors invisible or memory that is no longer accessible. This feature is the remedy to these problems that these errors can be stored in the instruments.

Source view
Sometimes when the person is the application that he wishes to see the view source code to detect the point of data or methods that use more CPU time. This is possible with this function the user can use the GUI tools. The user can identify the problem in the application and correct it so that the result is there in less time and is error free.

Low overhead sampling
We, as a user of new applications in the new iPhone will be like to know in advance the high fidelity of the implementation of the instrument. With this feature, the user may have the sample of performance data from the application of a simple key press with low overhead.

Custom Instruments
Users can build their own instruments using DTrace instruments and custom manufacturer according to their needs and requirements to raise their graphics performance with errors to a minimum.

System traces
The track system is the characteristic instruments with which records all information about all processes in the system and bottlenecks caused by the interaction of various processes with minimal resources.

Therefore, we can say that the instruments have characteristics very fascinating iPhone developers can outsource the development of the iPhone or iPhone development offshore. Thus, users can easily use these tools to complete their work in a jiffy and can give their best for companies.

Indonesia’s Minister of Industry, MS Hidayat, stressed the need for rules on the consumer goods entering the domestic market but is not produced in Indonesia, these products, especially low-technology, such as the Blackberry mobile phone made ??in Malaysia.

Blackberry production in Malaysia, but the market is precisely in Indonesia. Need some sort of additional tax or additional duties. Later there will be some sort of incentive or disincentive for such products, we must have rules or “barrier” with the aim that producers are more interested in doing production in Indonesia, MS Hidayat said.
